Abstract:
The title mol-ecular salt, C13H15N2 (+)·Br(-), crystallized with two independent ion pairs (A and B) in the asymmetric unit. In the cations, the planes of the pyridine and benzene rings are inclined to one another by 79.32 (8) and 82.30 (10)° in ion pairs A and B, respectively. In the crystal, the anions and cations are connected by N-H⋯Br hydrogen bonds, forming a centrosymmetric tetra-mer-like unit enclosing an R 8 (4)(16) ring motif. These units are linked via C-H⋯Br hydrogen bonds, forming a three-dimensional network.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
